Fuse Mounting On Battery Positive Pole (Xtm Only); Battery-Side Connection - Xtender XTS 900-12 User Manual

4.5.3 Fuse mounting on battery positive pole (XTM only)

A fuse delivered with the unit (XTM) can be mounted directly on the positive connecting pole to the
battery respecting the below stacking order.
The presence of this fuse does not exempt an installation of a protective device (fuse or circuit
breaker) as close as possible to the battery.
Be careful with the orientation of the ceramic washer. There is a small lip on one side, which
must fit into the M10 cable lug's hole.

4.5.4 Battery-side connection

Before connecting the battery, carefully check the voltage and polarity of the battery using
a voltmeter.
Incorrect polarity or over- voltage may seriously damage the device.
Prepare the batteries for connection: appropriate battery clamps, protection device (f), cable in
good conditions with correctly fitted clamps.
Fasten the negative cable on to the negative pole (-) of the battery and the positive cable on the
open protection device (f).
When connecting the battery, a spark may occur when connecting the second pole. This
spark is normal and due to the load of the internal filtering capacity of the Xtender even if
the unit is halted by the main on off command (1).
Regarding the connection of the battery, it is necessary to check that the parameter values
of the Xtender are consistent with the recommendations of the battery manufacturer. Non-
conforming values may be dangerous and/or seriously damage the batteries.
The default values of the battery's charge threshold level are shown in fig. 3a and specified in the
parameter table p.47. If they are not acceptable when compared to the battery manufacturer's
specification, it is necessary to modify them via the RCC 02/03 remote control before connecting the
voltage sources on the AC input (charger). Studer Innotec is not responsible for default values not
corresponding with the recommendations of the manufacturer.
If the factory settings are modified, the new values must be entered on the parameter table on p. 47
of this manual. The default values proposed by Studer Innotec are the usual values for lead acid
battery or gel batteries (VRLA or AGM).
The cabling and connection of the installation should only be carried out by an appropriately
qualified professional. The installation material such as cables, connectors, distribution boxes, fuses,
etc. must be adapted and must conform to the applicable laws and regulations the application
under consideration.
